IGNITER CAR FOR SINTERING APPARATUS.

Application led September 23, 1922. Serial No. 590,093.

To all lwhom z't may concern:

Be it known that we, THOMAS J. DAvIs and JOHN W. FoRsYTHzE, citizens of the United States, and residents of Duquesne and Willnsburg, respectivel in the county of Allegheny and State o Pennsylvania., have invented certain new and useful Imrovements in Igniter Cars for Sintering pparatus, of which the following is` a specification.

's invention relates to sintering Vapparticularly to igniter igniting the materials to has for one of its objects an igniter car having a body portion. That is a .body at is not movable vertically relapan.

Another object is to provide an improved igniter car that is composed of-fewer parts and is, therefore, more durable than those heretofore used.

be sintered, and the provision of stationar ignite;` car having the novel combination,

construction and desiign of parts describedl in the following spec cationand illustrated in the accompanyinlg drawings.

In the drawings 1igure 1 is a side elevation of the improved igniter car.

Figure 2 is an end elevation thereof.

Figure 3 is a top plan view of the car.

Figure4 is a longitudinal sectional elethe car, on the line IV-IV of Figure 3 showing it in position over a sintering pan.

Figure 5 is a cross sectional elevation 4on the line V-V of Figure 3.

ferring more particularly to the drawings, the numeral 2 designates a sintering panof ordinary and well known construc-A v tion, having aseries of grates 3 therein vthe ore, Hue dust, or the like for supportin which is designated by the to be smtere numeral 4.

The improved igniter car to which this invention `pertains comprisesa rectangular rigid body frame 5 of box girder construction, havlng flanged wheels 6 mounted on chine. are with gears 10 on countershafts 11 journaled .m

. v that such edge A still further object is to provide an f l provided 24. The shaft 23 is adapted to be rocked by a footA pedal 25.

The motor 17 receives its operating current from overhead conductors 26 `through trolley 27, and is' controlled by a controller 28 of any well known design.

Thewheels 6 ofthe igniter are adapted to travel on rails 29 arranged parallel with the longitudinal axis of the slntering pan, and the lower edge of the frame 5 is in such close proximity to the sintering pan will engage the upper surace of the material being sintered. Wear plates 30 are removably secured to the bottom face of the frame 5 so as to take the wear'caused by the igniter car passing over the material being sintered, and may be readily replaced as the frame becomes worn.

The side members of the frame 5 are with a longitudinalshelf 31 on which cross beams 32 are supported. The cross beams 32 are secured in position by bolts 33 and serve to brace and tie the frame together. supports.

The burner plates are divided into three groups, designated by the numerals 34, 34a and 35. The lates 34 and 34a are plain plates provided) with apertures 36 for the admission of air, while the plates are provided with air inlet apertures 37 and an enlarged burner receiving aperture 3 8, in which is mounted a gaseous fuel burner 39.

The burner plates 34 and 354 are provided along one side edge with a Bange" 40 adjacent -the upper face of the plate, and along the other side edge with upper and lower flanges 41 and 42. The flange 42 is substantially the same width as the flanges of the cross beams 32 for a purpose to be described.

Theburner plates 34a are, provided with the fianges 41 and 42, but are not provided with flange 40. The plates 34 are end Also they serve as burner plate platesand have their one side edge resting or supported on a rib or shelf 44 formed on the end beams of the frame 5.

The burner plates 34", as stated above, are end plates and are arranged between the end beams of the frame 5 vand the first cross beams 32. As thus arranged they have their one side edge supported on the rib 44 and their other side edge supported by the flanges 41 and 42, the flange 41 resting'on the upper face of the bottom flange of the beam 32, and their lower flange 42 projecting across the entire lower face of the bottom flange of the beam 32.

The burner plates 34 and 35 are arranged in alternate transverse rows across the device between the beams 32. The plates 34 and 35 are removably supported on the beams 32 by the flanges 40, 41 and 42. Tha-t is, the'flanges 40 of the plates rest on the upper faceof the lower flange of one beam, w ile the flange 41 rests on the upper face of the lower flange of the next adjacent beam, and the flange 42 projects under the complete lower face of the flange on the last named beam, thus protecting such flange from the intense heat generated by theburners.

The burners 39 have fuel pipes 45 connecting their upper en supply pipe 47. a he fuel supply pipe 47 has a flexible extension 48 on its outer end, to which is secured a quick detachable coupling member 49 adapted to be coupled to the fuel supply main 50. l

In the operation of the above described igniter, the body portion is not moved relative to the wheels as is necessary in most igniters heretofore used. The igniter is so constructedthat it is spaced only slightly above the sintering pan, and in order to seal the space between the igniter and pan it is only necessary to slightly heap or overill theI pan,

so that the igniter will be compelled to plow through the material in its movement over the pan, thus automatically forming a seal. Also during the operation if any of the burners become broken or clogged they may readily be removed without dismantling the apparatus.

The provision of the air inlet apertures in all the plates 34, 34a and 35 permits an abundance of air to support combustion of the material being` sintered. It also serves to compel a complete combustion of the gaseous fuel from the burners. .y

While we have shown only the preferred embodiment of our invention various modifications may be made'within the scope of the appended claims.

2. rlghe combination with a sintering pan adapted to support a quantity of material to be sintered, of an igniter comprising) a wheeled main frame, burners remova ly mounted on said frame, and means for supplying fuel to said burners, all arts of said igniter having a fixed vertica relation to said sintering' pan. i

3. The combination with a sintering pan adapted to support a quantity of material to be sintered, of an igniter comprisin frame, wheels on said frame, sai wheels being ixedly positioned on said main frame so that the lower edge of said main frame will be in close proximity to the upper face of said pan, a plurality of cross beams extending between the sides of said main frame, and burner platesfremovably mounted between said cross beams and supported on the lower flanges thereof.
